You cannot exactly upgrade it to get better gaming performance. The only thing you can probably do is upgrade the HDD to an SSD and add some RAM, but neither of those will help gaming performance that much.

Thanks for all the help so far guys, we'll definitely need to reconsider the amount of cities - we're 19 so will have time for another trip! The cities we definitely want to see are Paris, Barcelona, Rome, Munich, Berlin and Amsterdam, but even this seems a bit much from what you guys have said here. Been a brilliant help, thank you!

We did think 12 cities was pushing it for time - though the interrail ticket would start after Paris. We considered taking Florence and Vienna off this list, but apart from that we really would like to visit all the cities if possible. At the same time though we don't want to spend the trip rushing about. Do you think that we would have enough time if we got the month pass?

We've had a quick look at flights so far and it's around £50 to both Paris and Amsterdam (from Scotland) which is fine.

First, 8 GB of RAM is more than enough for every game out there. Second, you can upgrade the RAM on the MSI to even 32 GB if you wish (it has two accessible RAM slots). And third, the Nvidia GTX 950M GPU in the MSI is around three times more powerful than the AMD Radeon R7 M360 in the Lenovo.

Regarding MSI, they are pretty big. They are rather specialised in making PC gaming stuff. Motherboards, GPUs, gaming laptops and desktops and similar stuff.

Thanks for all your help! Sorry if the post was inaccurate, actual glass would be a possibility, the only restrictions are that it must be resistant to fuel exposure and transparent. Mechanical fixings would also be a possibility however I would rather stick to adhesives if possible.
